Try adding +over to your epsg definition of 4326. It fixed the problem for
me.
Mine looks like this now:
/usr/local/share/proj/epsg
4326 +proj=longlat +ellps=WGS84 +datum=WGS84 +over +no_defs
You might need to upgrade your version of PROJ4 for it to have an effect.

Hi
** **
I have an issue which seems to relate to tile-edge buffering and
world-view zoom levels.
** **
There's an example page at http://mapserver.magicsite.co.uk
** **
When you first visit the page, all seems normal, until you zoom out 1
level, at which point the tile which should sit over the west of the US
doesn't display.
From what I can see, when tile-edge buffering is ON and the tile next tile
wraps around the world, the tile in question is not rendered.
Turn edge-buffering off and that tile is rendered correctly.
Unfortunately, I'm in a position where I can't turn the buffering off.

from the mapfile:

METADATA
wms_title
wms_onlineresource
wms_srs EPSG:4326
tile_map_edge_buffer 9 # 9 pixel rendering buffer
http_max_age 86400
END
END

As far as I can tell, everything else is working correctly.
What I'm not clear on - is this a bug in the edge buffering within the
software, or am I doing something wrong?

The server running the example URL is currently using version 5.7-dev,
but the same issue is also apparent on a production server running v6.0.2*

Interested to know if anyone else has experienced the same issue?
